Testicular Metastasis in Renal Cell Carcinoma

We report on a patient, who was diagnosed with renal cell carcinoma (RCC) and presented with testicular metastasis at 5 years after the initial diagnosis, surgical interventions and systemic treatments. Although there are reports of testicular metastasis of RCC, to the best of our knowledge, our case is first who presented late recurrence in the testicular tissue despite previous tyrosine kinase inhibitor and PD1 inhibitor treatments.
